  SAP Error Message:
  WL001 Method &2->&1 produced an error
  
  Meaning / Cause:
  This error message indicates that a method call in an ABAP Object (class method) has failed or produced an error during execution. The placeholders &2 and &1 represent the class name and method name respectively, so the message essentially says:

  This usually happens when:
  
  The method encountered a runtime error (e.g., division by zero, null reference, database error).
  An exception was raised inside the method and not handled properly.
  The method logic failed due to invalid data or system state.
  There is a bug or inconsistency in the custom or standard code.
  
  
  Typical Causes:
  
  Programming error inside the method.
  Missing or incorrect data passed to the method.
  System or database inconsistencies.
